Mozambican Grass Seed Consumption During the Middle Stone Age -- Mercader 326 (5960): 1... - 0 views

    Mozambican Grass Seed Consumption During the Middle Stone Age
    Julio Mercader
    Science 18 December 2009:
    Vol. 326. no. 5960, pp. 1680 - 1683
    DOI: 10.1126/science.1173966

    The role of starchy plants in early hominin diets and when the culinary processing of starches began have been difficult to track archaeologically. Seed collecting is conventionally perceived to have been an irrelevant activity among the Pleistocene foragers of southern Africa, on the grounds of both technological difficulty in the processing of grains and the belief that roots, fruits, and nuts, not cereals, were the basis for subsistence for the past 100,000 years and further back in time. A large assemblage of starch granules has been retrieved from the surfaces of Middle Stone Age stone tools from Mozambique, showing that early Homo sapiens relied on grass seeds starting at least 105,000 years ago, including those of sorghum grasses.

Observations: Humans feasting on grains for at least 100,000 years - 0 views

  •  
    "Grains might have been an important part of human diets much further back in our history than previous research has suggested.

    Although cupcakes and crumpets were still a long way off during the Middle Stone Age, new evidence suggests that at least some humans of that time period were eating starchy, cereal-based snacks as early as 105,000 years ago. The findings, gleaned from grass seed residue found on ancient African stone tools, are detailed online Thursday in Science.

    Researchers have assumed that humans were foraging for fruits, nuts and roots long before 100,000 years ago, but cereal grains are quite a new addition to the early prehistoric gastronomic picture. "This broadens the timeline for the use of grass seeds by our species," Julio Mercader, an assistant professor at University of Calgary's Department of Archeology and author of the paper, said in a prepared statement.

The Heart Scan Blog: This is your brain on wheat - 0 views

    "Here's just a smattering of the studies performed over the past 30 years on the psychological effects of wheat consumption.

    Oddly, this never makes the popular press. But wheat underlies schizophrenia, bipolar illness, behavioral outbursts in autism, Huntington's disease, and attention deficit hyperactivity disorder (ADHD).

    The relationship is especially compelling with schizophrenia:

    Opioid peptides derived from food proteins: The exorphins.
    Zioudrou C et al 1979
    "Wheat gluten has been implicated by Dohan and his colleagues in the etiology of schizophrenia and supporting evidence has been provided by others. Our experiments provide a plausible biochemical mechanism for such a role, in the demonstration of the conversion of gluten into peptides with potential central nerovus system actions." "

THE LECTIN STORY - 0 views

  •  
    "While research in lectinology is in its infancy this information is critical to your health and it is important to begin to understand lectins NOW. Read the following report carefully. I'll get specific about how this all applies to you. ALL foods contain lectins. Some are your friends, others neutral, and others may be your enemies. Know your lectins. Avoid your enemies.

    DEFINITION
    Protein or glycoprotein substances, usually of plant origin, of non-immunoglobulin nature, capable of specific recognition of and reversible binding to, carbohydrate moieties of complex glycoconjugates without altering the covalent structure of any of the recognized glycosyl ligands. This group includes monovalent lectins (i.e. bacterial and plant toxins). These lectins bind to sugar moieties in cell walls or membranes and thereby change the physiology of the membrane to cause agglutination, mitosis, or other biochemical changes in the cell. (agglutination- clumping; mitosis-multiplication or division of a cell forming two daughter cells)

    High levels of lectins (specialized proteins) may be found in grains (also known as cereals or pulses), legumes (that is 'beans' including peanuts), dairy and plants in the nightshade family. Many other foods contain lectins but are less well studied and the amounts of lectins present are not thought to be as high or as potentially toxic.!

Schizophrenia and Gluten - NephroPal: Schizophrenia - 0 views

  •  
    I have been reading a case report by Kraft, Westman, 2009 of a 70 year old obese, Caucasian female who was suffering from Schizophrenia since the age of 17. Her symptoms included paranoia, hallucinations (auditory and visual), and many hospitalizations for psychosis and suicide attempts. Her daily diet included "egg and cheese sandwich, diet soda, water, pimento cheese, barbecued pork, chicken salad, hamburger helper, macaroni and cheese, and potatoes." Instead, she was asked to follow a low carbohydrate diet of: "unlimited meats and eggs, 4 ounces of hard cheese, 2 cups of salad vegetables, and 1 cup of low carbohydrate
    vegetables per day. This diet restricts carbohydrate intake to fewer than 20 grams per day." The diet was also grain free.

The Heart Scan Blog: Beating the Heart Association diet is child's play - 0 views

    In response to the Heart Scan Blog post, Post-Traumatic Grain Disorder, Anne commented:

    While on the American Heart Association diet my lipids peaked in 2003. I even tried the Ornish diet for a short time, but found it impossible.

    Total Cholesterol: 201
    Triglycerides: 263
    HDL: 62
    LDL: 86

    After I stopped eating gluten (I am very sensitive), my lipid panel improved slightly. This past year I started eating to keep my blood sugar under control by eliminating sugars and other grains. Now this is my most recent lab:

    Total Cholesterol: 162
    Triglycerides: 80
    HDL: 71
    LDL: 75

    Dietary acid-base balance, bone resorption, and calcium excretion.

    J Am Coll Nutr. 2006 Jun;25(3):224-30.

    Conclusions: Diet changes that increase renal NAE are associated with increases in serum PTH, bone resorption, and calcium excretion over a 60-day period.

    Eating healthy sounds like a good idea in theory, but when sticking to your budget is as important as it is during this economic crisis, it's often easier to pick up the cheapest foods at the store. These 50 foods, however, prove that nutrition doesn't have to be as expensive as you think.

The Heart Scan Blog: Can millet make you diabetic? - 0 views

  •  
    If wheat is so bad, what about all the other grains?

    First of all, I demonize wheat because of its top-of-the-list role in triggering:

    --Appetite--Wheat increases hunger dramatically
    --Insulin
    --Blood sugar--Wheat is worse than table sugar in triggering a rapid, large rise in blood sugar
    --Triglycerides
    --Small LDL particles--the number one cause for heart disease in the U.S.
    --Reduced HDL
    --Diabetes
    --Autoimmune diseases--Most notably celiac disease and thyroiditis.

    Most other "healthy, whole grains" aren't quite as bad. It's a matter of degree.

    Can including wheat in your diet create hell on earth?

    Was The Inferno nothing more than Danté's prediction for the state of the U.S. diet circa 2009?

    I'm kidding on The Inferno allusion, but the American diet nonetheless sure does create an inferno of unhealthy phenomena.

The Heart Scan Blog: What your doctor doesn't know about heart disease - 0 views

    What causes coronary heart disease or coronary atherosclerotic plaque, this thing that we track with heart scans?

    Well, here are a few little-publicized facts about heart disease that you are unlikely to hear from your When's-the-next-stent? cardiologist or the What is there besides statins? primary care doctor.

    (Since everybody knows that smoking is a modifiable risk for heart disease that can be readily identified, let's focus on the blood tests that reveal heart disease causes.)

Should you follow a no-grain diet? - 0 views

  •  
    The No-Grain diet is based on the idea that grains and sugars are "enemy number one to losing weight and living longer."

    Instead, The No-Grain diet emphasizes organic vegetables and quality protein.

    It's true that refined grains - such as white bread, white rice and many breakfast cereals - contain many calories, but without the fiber, vitamins, and minerals found in whole-grains.

    In other words, they're energy-dense but nutrient-sparse.

    But it's worth pointing out that there's a difference between whole grains and refined grains.
